An apparatus comprising a pair of inverters configured in a cross-coupled configuration, wherein an inverter of the pair of inverters comprises a static random-access memory (SRAM) physically unclonable function (PUF) circuit, wherein the SRAM PUF circuit comprises an inverter; and an inverter cell comprising a p-channel metal-oxide-semiconductor (PMOS) transistor, an n-channel metal-oxide-semiconductor (NMOS) transistor, and output node, and a control signal input, wherein: (i) the PMOS transistor comprises (a) a drain terminal that is coupled to an output and (b) a source terminal that is coupled to a supply voltage, (ii) the NMOS transistor comprises a gate terminal that is coupled to a gate of the PMOS transistor that inhibits a path between the supply voltage and ground, and (iii) responsive to a low state provided to the control signal input, the control signal input causes the PMOS transistor to charge the output node to the supply voltage.
